OEIS Sequences

a(n) = a(n-1) + a(m) for n >= 3, where m = 2^p+1 + 2 - n and p is the unique integer such that 2^p < n - 1 <= 2^p+1, starting with a(1) = 1 and a(2) = 3. A50069

Numbers k such that k divides ∑_j=1..k j^j = A001923(k). A128981

a(1) = 1; thereafter a(n) is always the smallest integer > a(n-1) not leading to a contradiction, such that any four consecutive digits in the sequence sum up to a prime. A152604

Discriminants of imaginary quadratic fields with class number 42 (negated). A351680

Let p = n-th prime of the form 4k+3, take the solution (x,y) to the Pellian equation x² - p·y² = 1 with·and smallest y >= 1; sequence gives value of y. A82394

Numbers k such that A163511(k) is a fifth power. A365802

a(1) = 2, and for n>1: a(n) = prime(A251719(n)) * prime(A251719(n) + n - 2), where prime(n) gives the n-th prime. A251724

a(n) = 12167·n - 8579. A156845

a(n) = 12167n - 3588. A156846
